ATTORNEYS AIR FILTER AND DEFLECTOR WITH ENCLOSED MAGNET MOUNTS BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to .air deflectors with filters for air outlets in heating and cooling systems, and more particularly, to deflectors and filters'having adjustable lengths.

2. Description of the Prior Art In the US. Pat. No. 3,225,679 issued to Christoph P. Meyer is disclosed an air deflector which canbe conveniently and quickly installed in operative relation to an air register. In the U.S. Pat. No. 3,358,578 also issued to Christoph P. Meyer there is disclosed an air deflector having magnetic mounts for the mounting of the deflector to an air register. Disclosed inthis application is yet another air deflector which has a removable filter for cleaning theair as it passes from the air register and through the deflector. The deflector and filter disclosed herein are telescopically constructed so as tofit a variety of different sized air registers.

SUMMARY OF THE INVENTION One embodiment of the present invention. is an air filter deflector mountable adjacent a register compris ing a main body having a pair of spaced apart side walls and air deflecting wall means connected to and between the side walls, a filter frame removably mounted to the deflector between the side walls, and, air filter means mounted to and'across the frame.

It is an object of the present invention to new and improved air deflector.

It is a further object of the present inventionto, provide an air deflector having an improved air filter.

Yet another object of the present invention is to provide an air deflector with filter which may be quickly and easily sized to fit an air register.

Related objects and advantages of the present'invention will be apparent from the following description.

BRIEF DESCRIPTION OF THE DRAWING.

FIG. I isa perspective view of an air deflector and filter incorporating the present invention shown mounted to an air register.

FIG. 2 is an enlargedcross-sectional view taken along the line 2-2 of FIG. 1 and viewed in thedirection of the arrows and is rotated 90 counterclockwise.

provide a FIG. 3 is an enlarged plan view of the filter 40shown DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting an understanding of the principles of the invention, reference will. nowbe; made to the embodiment illustratedin the drawingandspecific language will be usedto describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applicatons of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring now more particularly to FIG. 1, there is shown an air deflector 21 removably mounted to an air register 20. A filter 40 is removably mounted within deflector 21 for cleaning the air as it passes from the register in the direction of arrow 22. Deflector 21 has a main body with a pair of spaced apart side walls 26 and 27'. A,pair of magnets 23 are mounted on walls 26 and 27 for the removable mounting of the deflector to the air register. Magnets 23 are mounted to the side walls in a manner identical to that disclosed in the previously listed US. Pat. No. 3,358,578. Incorporated herein by reference is the disclosure of the US. Pat. No. 3,358,578 issued to Christoph P. Meyer and entitled AIR DEFLECTOR WITH ENCLOSED MAGNET MOUNTS relative to the magnets and side walls disclosed therein.

A curved wall having a left section 24 and a right section 25, as veiwed in FIG. 1, is integrally connected to the side walls with the left section 24 connected to side wall 27 and with the right section 25 connected to side wall 26. The right wall section 25 slidably receives and passes beneath the left wall section 24. Referring to FIG. 2, inner wall 28 corresponds to the right wall section 25 of FIG. 1 with the outer wall 29 corresponding to the left wall section 24. Walls 28 and 29 are complementary in shape each being integrally joined at an end to one of the side walls. Wall 28 has a lower edge which is curved upwardly to form lip 31 and recess 32. Likewise, the upper edge of wall 28 forms lip 33 and recess 34. The lower tapered edge of wall 29 is slidably received in recess 32 whereas the upper off-set edge 37 of'wall 29 is slidably received in recess 34. Recesses 32 and 34 extend longitudinally along the length of wall 28 so as to allow walls 28 and 29 to be telescoped to the appropriate size corresponding to the length of register 20;, A pair of longitudinally extending upraised ridges 35 and 36 are formed on the outer surface of wall 28 adjacent, respectively, recesses 34 and 32. Ridges 35 and 36 space walls 28 and 29 apart thereby reducing the friction resulting from the sliding motion therebetween.

Filter 40 is also telescopically constructed along with the main body of the air deflector. Filter 40 (FIG. 3) is rectangular and has a pair of frame members 41 and 42 with member 42 also being shown in FIG. 4. Frame member 421 has a pair of longitudinally extending severagle parallel side rails 53 and 54 integrally joined together and spaced apart by at least three cross struts which are shown'as struts 55, 56 and 57. A pair of ledges 58and 59. (FIG. 5) are respectively formed on rails 54 and 53 and are slidably received, respectively, by guides 48 and 47 integrally connected to frame member 41. Frame member 41 is shown in FIG. 6 with an end view thereof shown in FIG. 7. Frame member 411 has guides 47 and 48 integrally connected thereto with recesses 49 and being provided in guides 47 and 48 for receiving ledges 59 and 58. A porous synthetic foam-like material coated with silicone is secured to frame member 41 by adhesive or other suitable means and is shown by item number 43. An identical material 44 is secured to frame member 42. The filter is removably mounted to side walls 27 and 26 which are provided with slots 30 (FIG. 1) which receive, respectively tabs 45 and 51 (FIG. 3). Upraised tits 46 and 52 are formed on tabs 45 and 51 to abut against the outside surface of walls 27 and 26 thereby resisting relative movement between the tabs and side walls. Tabs 45 and 51 extend lockingly and removably through the side walls of the deflector. The guides 47 and 48 have not been shown in FIG. 1 for sake of clarity.

Frame member 42 may be cut with a sharp instrument; such as, a pair of scissors for sizing the filter to the respective air register. For example, rails 53 and 54 may be severed immediately adjacent to cross strut 56 leaving strut 56 connected to the frame and allowing strut 55 to be discarded. Thus, the length of frame member 42 is reduced allowing the filter 40 to be of a smaller length without excessive overlapping of filter materials 43 and 44. It is desirable to reduce the overlapping of filter materials 43 and 44 so as to not retard the air flow and to achieve a uniform air flow across the air filter.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. A variety of materials may be used to produce the main deflector body and the frame. Excellent results have been obtained by producing the deflector body and filter frame from plastic.
